We used satellite telemetry to study behavior at foraging sites of 40 adult female loggerhead sea turtles (Caretta caretta) from three Florida (USA) rookeries. Foraging sites were located in four countries (USA, Mexico, the Bahamas, and Cuba). We were able to determine home range for 32 of the loggerheads. One turtle moved through several temporary residence areas, but the rest had a primary re...

– Great progress has been achieved in face recognition. But it is still challenging to differentiate the people with similar appearance and to recognize the same person who has different appearance due to different facial expression, pose, occlusion, illumination and aging. This paper provides some of the local feature based methods that tackle these problems. The two main approaches of local f...

High-resolution models can reproduce mesoscale dynamics and the variability in the Gulf of Mexico (GOM), but cannot provide accurate locations of currents without data assimilation (DA). We use the computationally cheap Ensemble Optimal Interpolation (EnOI) in conjunction with the Hybrid Coordinate Ocean Model (HYCOM) model for assimilating altimetry data. The covariance matrix extracted from a...

There are over 2300 standing oil and gas platforms in the northern Gulf of Mexico (GOM). It has been argued that platforms provide reef-like habitat that increases the growth and survival rates of fishes by increasing prey availability and affording shelter for protection from predators, provide additional spawning substrate, and by acting as a visual attractant for organisms not otherwise depe...

Millions of barrels of oil escaped into the Gulf of Mexico (GoM) after the 20 April, 2010 explosion of Deepwater Horizon (DH). Ocean circulation models were used to forecast oil slick migration in the GoM, however such models do not explicitly treat the effects of secondary eddy-slopes or Mississippi River (MR) hydrodynamics. Here we report oil front migration that appears to be driven by sea s...

tivity phenomenon that is widely accepted as indicating the base of the gas-hydrate stability zone. The acoustic impedance difference between sediments invaded with gas hydrate above the BSR and sediments without gas hydrate, but commonly with free gas below, are accepted as the conditions that create this reflection. The relationship between BSRs and marine gas hydrate has become so well known...

Estimation of net-to-gross (N/G) on a field wide scale was accomplished by integrating rock property trends and high quality 3D seismic data. Edited and anisotropy-corrected sonic logs from deepwater Gulf of Mexico (GoM) were used in combination with core velocity measurements and Biot-Gassmann modeling to determine shale and oil sand trends in low-frequency Vp-Vs space. These trends equally ap...

In an attempt to fill a gap between fully automatic search/match programs and purely manual methods based on paper products, a relational database plug-in has been developed that functions as a PC-based Search/Index program for extracting information from PDF-4 powder diffraction databases. The plug-in provides an adjustable search window and match window to account for experimental errors. Bot...

The purpose of this study was to increase our understanding of the gaseous elemental mercury (GEM, Hg◦) fluxes between the atmosphere and soils. Moreover, we wanted to quantify the annual GEM flux, identify the controls, and compare the GEM flux to annual rates of gaseous oxidized mercury (GOM) dry deposition and wet deposition of total mercury. We measured GEM fluxes using the modified Bowen r...

Recently, tilted transverse isotropic (TTI) imaging has become a standard practice in deep water Gulf of Mexico (GOM) to resolve the anisotropic effects of wave propagation in salt-withdrawal mini-basins. Compared with isotropic and vertical transverse isotropic (VTI) imaging, TTI prestack depth imaging generally provides flatter common image gathers (CIGs) for WAZ data, improves image focusing...
